Is a night guard covered by dental insurance?
Sometimes. Night guards split plans down the middle: many exclude them outright, and the plans that do pay usually cover about half the fee, once every few years, often only when grinding damage is documented. A hard night guard (code D9944) is a custom-made rigid guard that covers every tooth on one arch, worn while you sleep to protect the teeth from clenching and grinding.
50% or $0
Excluded on many plans, half on others
3 to 5 years
Where covered, most plans pay for one guard per 3 to 5 years, hard or soft. A replacement inside the window is cash, even if the dog ate it.
Proof of grinding
Some plans pay only when the chart shows wear or fractures from grinding. Without that note, a covered plan can still deny the guard.
Counts toward max
A covered guard at 50% still draws from the annual maximum. Late in the year, after a crown, the plan's half may be smaller than the patient expects.
Most-asked code
Night guards are one of the most-asked coverage questions at the desk, and the answer is never safe to guess. Checking D9944 against the plan takes under a second.

When D9944 is the right code
- A rigid, custom-fitted guard, not a store-bought tray
- Covers all the teeth on one arch
- Made to protect against clenching and grinding
- Worn at night, not a sports mouthguard
Documentation payers expect
Notes describing wear, fractures, or other grinding damage, plus the arch and the material. Some plans want a prior authorization or a narrative before they pay.
Why night guards get denied
What happens after the night guard
The guard is the cheaper half of the story. Patients who grind often arrive with the damage done, so the next quotes are a crown (D2740) on a cracked tooth or a core build-up (D2950), both usually major-class at around half. If the plan paid 50% on the guard, that money came out of the same annual maximum the crown needs. The desk that ran the check on day one knows the remaining maximum and can time the guard and the crown across two plan years.
D9944, quick answers
Does dental insurance cover a night guard?
Sometimes. Many plans exclude D9944 entirely, and the ones that cover it typically pay about 50% once every 3 to 5 years.
How often will a plan pay for a new guard?
Typically once every 3 to 5 years where covered, and the window is shared with a soft guard (D9945).
Does the plan need proof that I grind my teeth?
Some plans do. They look for wear or fractures in the notes before paying, and deny a guard ordered only for comfort.
Is a hard guard covered differently than a soft one?
Usually the same benefit and the same frequency. The plan pays one guard per window regardless of material.
How do we quote a night guard without guessing?
Check D9944 against the patient's plan before you quote. The check shows covered or excluded, the percentage, and the remaining maximum.
